Hello bitcoin forum! Haven't posted here in a while...

I have recently bought my "new" gaming PC. Parts are used so, it's not new, but it's new and beefy for me.


MOB: MSI Z77-G55A
RAM: 8GB DDR3 Patriot
CPU: i5 2500K
GPU: RX580 8GB (Sapphire Nitro+, samsung)
SSD: Patriot 250GB
PSU: beQuiet! Dark Power Pro 10


Parts costed me ~400$ total. Since I was caught in some deep shit with drugs, lost my gaming and mining PC to it, I was finally able to overcome that and I'm making a slow but steady comeback.

I figured I could mine and trade a little bit until I make back 100$ which is how much my GPU costed me, and I'm planning to buy another one, and make a Gaming + Mining PC all-in-one. I mostly just write code on my PC, and my GPU has been mining for about 2 weeks now and I'm happy with its performance. This specific model runs pretty cold for an AMD polaris card (or is it polaris, I'm kind of losing track with all these GPU releases in the past couple of years...)

I'm mining ethereum solo with good ol' claymores software through nicehash, where I also trade other crypto, make 1000-2000 satoshi here and there mostly for fun, but who knows

Only thing I can't seem to figure out is the most optimal clocks for mining. I know I can't use furmark, ashes of the benchmark or other GPU stressers because gaming and mining are not the same. I'm getting around 6-7 rejected shares / 24h and I'm not sure whether this is OK. My current mining mode OC is:

MEM: 2100MHz @ 850mV
CORE: 1108MHz @ 850mV
Mode is also changed to compute in adrenaline. No bios mods have been done. Guy who sold me the GPU was also using it for mining and he took good care of this puppy.

I have figured that increasing only memory clock doesn't doo much unless I bump core clock a little bit too. My default mV for memory is 950 which I use to play games with, and I used this mV to mine until today, I have lowered it to 850mV and it feels the same (but 95w to 77w baby, that's money right there!)

How do I know if things get unstable? My previous 6x 1050ti rig would just completely freeze the OS. Their memory clock would easily bump to max because nVidia, so I only had to tweak core clock to find a sweet spot... But with this card I don't get no crashes / bsods, rejected shares ~6/24h with any voltages and clocks I've tried so far, I'm not sure how I can fine tune this to the max.

Also, one last question, this asshole sold me his "modular" psu with only mobo, cpu, and 2 peripheral cables. So I had to buy some shitty sata > 6pin and 8pin pci-e to hack my way into making my GPU run. Anyone has any idea where I could buy cables for my PSU (don't wanna pay 100$ for cablemod when I could get a brand new PSU for that money). I don't want to resell this PSU to anyone in this state (and I'm planning on replacing it in the future), and it's a pretty quality PSU so if I could get the missing cables for cheap that'd be a BOMB.

Thanks for reading, share your thoughts and opinions, everything is welcome! Have a nice day!

What's the point of altcoins? Doesn't decentralization mean that everyone can join and work on the project regardless of anything? So why aren't some of the greatest minds, like Vitalik or Charles working on improving bitcoin? Why do we f!@#$ng have 1600 crypto currencies in the space? I only see ads with "hello we built this awesome currency that does this and does that" for what? We already have bitcoin! I know it's old and rusty, but that's why you develop, and that's why you rework.

I'm a developer myself. I have re-built my game from ground up three times now. Just because I wrote it badly, doesn't mean I have to release it and not put anything new because I'd completely break it. I'm sure there are workarounds, even if we have to fork the coin, and start from scratch.

But instead, we have groups of people who fork coins and state that they are doing something awesome, while they aren't. And we ended up with 169 different bitcoins, and 1400 other (bit)coins as well, which is really hurting my feelings.

And now we even have companies like bitmain, who, in my honest opinion have completely destroyed the whole concept of decentralization.

My take on all this fuss is that, crypto is in a really bad position. Don't get me wrong. The technology IS revolutionary. It's just that humanity is just not ready yet for such a thing, as greed and selfishness are still ruling our realms.

And by the looks of it, I don't think humanity will ever be ready for this.

It's all about the fucking money. And if someone tells me otherwise, I'm sorry but I'd really slap him.

Thanks for reading!

[Rig]

Hello Forums,
I have built my first mining rig, I went for a little bit cheaper option with 2 cards only because I wanted to see how it goes before I blow more money into this. I ordered 4 more of these cards, along with 6 risers.

Rig

- Asrock Fatal1ty H270 Performance,
- Kingston Hyperx Fury 4GB DDR4,
- Intel Celeron G3920 Dual-Core,
- Radeon SSD 120GB
- ASUS GTX 1050ti Expedition 4GB x6 + 6 Powered 1x -> 16x Risers,
- Corsair RM750i 750w 80Gold

Total cost: 1650$

Set Up

BIOS Settings

• Update BIOS using EZ Flash
• Above 4G Decoding - Enabled
• Top of low usable drain - 3.5GB

Unless you set the settings like these there is a high chance your RIG wont even boot.

Windows 10 - Low Hash Rate, around 2.2 MH/s per card. Maybe I should've updated Windows, but gave up on it quickly.

Windows 8.1 - Installing windows 8.1 fixed the low Hash Rate for me. Setting the EthDcrMiner64.exe's priority to Realtime in Windows Task Manager, my Hash Rate stabilized to "maximum possible", never dipping below that even when playing games (using Intel's HD integrated GPU for games, of course).

NVIDIA Driver - Install the newest driver from NVIDIA website. Current newest is: 384.76 for 1050ti. Any driver does the same so don't worry. If you want to update your driver, first download DDU to uninstall previous driver with it. It is highly recommended.

Miner config

Code:

-mode 0
-dcoin dcr

-epool eu2.ethermine.org:4444
-ewal wallet.worker
-epsw x

-dpool dcr-eu.coinmine.pl:2222
-dwal coinmineUsername.worker

Overclocking
- Power Limit: 100%,
- Temp Limit: 83*C,
- Fan Speed: 10*C = 10%, 20*C = 20%... N*C = N%

This is all that I've found out so far about OC-ing the cards for mining.

• In case you are mining ETH / ETC only, pull the Core all the way back to -400 (Lowest), and Memory to +1000 (max) on each card, but on the last, 6th card. I've found out that all of my cards actually work fine with max OC on the Memory (even though it's Micron), but the last one crashes the entire system if set above +850. Core clock has absolutely no influence when you mine ETH / ETC only, so lower it down to minimize W drain and cards temperatures.
  ETH ONLY: 94 MH/s (15.5 MH/s per card)
• In case you are mining ETH / ETC + DCR / SC... You need to up the Core high now. Maximum stable I god today is +225 to the Core, and +1000 to the Memory (except the last card which is at +850 Memory) Core clock seems very significant when dual-mining.
  ETH + DCR: 82.5 MH/s (13.8 MH/s per card), 1650 MH/s (280 MH/s per card)

Thanks for reading, have a nice day

Gear I wish to purchase is:

GPU: MSI R9 380 4GB GDDR5 @ ~190$
 - How much GPUs should I buy? I'm thinking of going 4.

CPU: Intel Pentium G3240 @ ~60$
 - I suppose I don't need to blow cash on CPU as I'm only going to be using it to run the miner rig.

RAM: Kingston FuryX Red 2x4GB DDR3 @ already owned
HDD: 250 GB WD Blue @ already owned
 - I have a dead PC laying around, so I suppose I could save some extra cash if I used these components I already own. I can also sell my old MOBO from this PC as it only supports 1 GPU, as well as a power supply to get ~40-50$ from that back, too.

PSU: EVGA G3 850W @ ~160$
 - Should this be enough to run 4 of the GPUs I intent to buy? If not, I could buy a EVGA G3 1000W @ ~220$ as well.

MOBO: I have no clue which motherboard to buy, but I assume that the one which would support 4 way crossfire would be around 100$-150$ range. If you could help me choose that'd be awesome.

So buying 4 of these cards and everything else (calculated with the 1000W PSU just in case) would cost me ~1150$
Bitmain Antminer S9 would cost me ~1450$ including their PSU and shipping costs.

So the PC mining rig would cost me 300$ less, and calculating my profits here https://www.cryptocompare.com/mining/calculator ,
with 4 of these cards I'd be earning 0.056 ETH daily. 0.08$ per kW/h is the electricity cost here. So the rig would mine just a little bit less $ in ETH daily than the Antminer S9 would mine $ in BTC, costing me 300$ less as a huge bonus.

What do you guys think? I need professional opinion before I blow up all my savings lol
